For those who still want to hang on to CDMA based handsets can approach nearest BSNL CSC and collect new prepaid/new postpaid or CDMA MNP blank sim cards. BSNL RUIM work on most Sprint/USC/Verizon phones. BSNL has very cheap 1x and evdo plans beneficial for users owning handsets like Tribute, HTC 510, LG Volt2 etc. Tata Indicom also gives out all services and there has not been any public notice of it's closing down. If any Tata Indicom store person refuses to provide MNP sim or prepaid or postpaid, make a call to Tata cc and they will ask the store guys to give. I will provide some assistance to RCDMA subscribers from Gujarat willing to port to any of the above.
